Ah right. You can only get an anonymous tuple_like<int, int> type, not X1.
But isn't this still better than flattening? You could print it as { { 1, 2
}, { 3, 4} }, instead of { 1, 2, 3, 4 }.

That's one of the options. Some time ago I thought that is it less usefull
than returning flattened type. Nowadays there's a precise reflection that
does a lot of things much better, so I see no big need in improving flat
